Testing how to diagnose fungal sinus infections
This study looks at better ways to diagnose a fungal (mycotic) infection in the sinus/near-nose area. You may be considered if you have symptoms on only one side, such as blockage or drainage, and you can safely take part in the study tests.

Study of controlled Shigella infection in Kenyan adults
This Phase 1 study gives a carefully measured dose of Shigella sonnei to healthy adults to learn about the infection’s safety and how the body responds. It may help researchers build safer future tests or treatments, but it requires a hospital stay and many follow-up visits.
KilifiAges 18–45 - NCT05961059RecruitingPhase 1
Shigella vaccine safety study for healthy adults

LeidenAges 18–50 - NCT05963711Recruiting
Study penis microbiome in partners during vaginal microbiome treatment
This study looks at how the bacteria on a man’s penis may change during a woman’s vaginal microbiome transplant (VMT) for recurrent bacterial vaginosis (BV). You may be asked to follow condom and “decolonization” steps to help the researchers understand what works and why.
JerusalemAges 18 years+ - NCT05964140RecruitingPhase 3
Testing antibiotics after jaw fracture surgery
This trial studies whether giving (or how giving) antibiotics affects outcomes after surgery for a broken lower jaw (mandible). It may help reduce infection risk and antibiotic-related side effects if the right approach is chosen for the right patients.
Blackburn, LancashireAges 18 years+ - NCT05966649Recruiting
Synbiotics for preventing preterm birth in higher-risk pregnancies
This trial tests whether taking synbiotics (a mix of “good” probiotics and “food” for them) can help lower the chance of going into labor too early. It’s for pregnant people with certain risk factors for preterm birth, and it compares outcomes while you follow the study plan.
Edegem, AntwerpenAges 18 years+ - NCT05966961Recruiting
Compare two stitches to close surgical wounds
This trial compares two types of dissolvable stitches to close wounds after abdominal (belly) surgery done through open surgery or small incisions. It aims to see which stitch option works better or is safer for healing and recovery.
NaplesAges 18 years+ - NCT05968573Recruiting
Health messages intervention for people at risk of HIV or HCV
This study tests whether persuasive, health-message coaching can help people reduce risk for HIV or hepatitis C (HCV). You may be eligible if you’re not infected with HIV or HCV and haven’t been tested for either in the last year.
New York, New YorkAges 18 years+ - NCT05968742Recruiting
Study of how gums respond to irritation
This study looks at how your gums react when exposed to a controlled irritant, comparing different gum response patterns. It may help researchers understand why gum inflammation happens and how to prevent it.
Seattle, WashingtonAges 18–35 - NCT05969275RecruitingPhase 2
Cell therapy trial for infection-related septic shock in ICU
This Phase 2 trial tests an immune-boosting cell therapy (umbilical mesenchymal stromal cells) in people with septic shock—when infection causes dangerous stress on the heart and other organs. The goal is to see if this treatment can improve outcomes compared with standard care.
Ottawa, OntarioAges 18 years+ - NCT05970965Recruiting
Teeth and gum study in children with Down syndrome
This study looks at how gums and inflammation work in children with Down syndrome by collecting and analyzing biological samples. It may help researchers understand gum health differences and improve future care.
Ivry-sur-SeineAges 3–12 - NCT05972772RecruitingPhase 2/Phase 3
Test study drugs to clear rickettsia infections
This study tests antibiotics to help your body clear rickettsia-related illnesses like murine typhus or scrub typhus. It may help reduce symptoms and shorten how long you feel sick, based on how well the infection clears.
Vientiane, VientaineAges 18 years+ - NCT05973084Recruiting
COVID spread study in Malawi households and vaccine recipients
This study tracks how COVID-19 spreads and causes illness in real households in Blantyre, Malawi, and compares groups after infection or vaccination. If you qualify, you’ll do follow-up testing and visits for several months.
Boston, MassachusettsAges 5–75 - NCT05975671Recruiting
Survey in pediatric ICU to reduce upfront vancomycin use
This study is a survey and quality-improvement effort in participating children’s intensive care units. It aims to understand and change how doctors decide to start vancomycin (an antibiotic) when sepsis is suspected, to improve care and avoid unnecessary use.
Atlanta, GeorgiaAges Any age - NCT05977179Recruiting
Diet program for long-COVID fatigue and poor diet quality
This study tests whether improving diet quality can reduce fatigue and symptoms in people with long-COVID (post-acute COVID-19 syndrome). It may help if your diet quality is currently low and your fatigue is moderate to severe.
Baltimore, MarylandAges 50–94 - NCT05977283Recruiting
Follow-up study for people whose hepatitis B test improved
This study follows people with hepatitis B (HBV) blood tests that have improved over the last year. It aims to learn what happens after the hepatitis B surface antigen (HBsAg) goes down, and may help doctors better predict outcomes.
Guangzhou, GuangdongAges 18–65 - NCT05979545RecruitingPhase 4
Early treatment with ceftazidime-avibactam for serious infections
This study tests an antibiotic called ceftazidime-avibactam for people with serious infections like bloodstream infections or pneumonia that started in the hospital or from a breathing machine. It aims to start treatment quickly after identifying the bacteria.
